Macron is a fool. He suspended the tax for 6 months, yea, he's never going to be able to enact it now. Plus he have in to one demand so now everyone knows they can get whatever they want from him. The real mistake of course was pushing too far in the first place. At some point people will push back and once that happens, all is lost. He might as well resign now.

I heard from a friend in France that some police have defected and joined the protests. I'm not sure how true that is, but either way, I suspect that Macron's reversal of the tax hike won't matter. The ball is already rolling, and it's going to end up somewhere.
